Definitions

  • the present disclosure relates to an intake structure of a vehicle and a method of mounting a nipple to the intake structure, and more specifically, to an intake structure of a vehicle with a nipple to prevent engine oil from flowing back along the nipple and a method of mounting the nipple to the intake structure, which prevents the oil contained in a blow-by gas from flowing into a fresh air nipple which supplies a fresh air to an engine or a brake booster.
  • Intake air is supplied to a combustion chamber for combusting fuel.
  • An intake pipe is mounted in the engine for supplying the intake air.
  • the intake pipe includes an intake shield, an intake duct, an air cleaner, and an intake hose.
  • the intake hose is connected to a surge tank, an intake manifold, and the like.
  • a compressor of a turbo charger is mounted at the front end of the surge tank or the intake manifold, the compressor of the turbo charger and the intake hose are connected to each other.
  • a pressure which is equal to or greater than atmospheric pressure is generated between the compressor of the turbo charger and the engine by the operations of a turbine and the compressor configuring the turbo charger.
  • a circulation line which circulates the intake air is mounted between the front end and the rear end of the compressor of the turbo charger.
  • the circulation line is mounted with a pressure-sensitive valve. The pressure-sensitive valve is operated to open when the inner pressure of the circulation line is a particular value or greater, and maintains the locked state when the inner pressure is less than the particular value.
  • the inlet pressure of the compressor of the turbo charger may be greater than the outlet pressure thereof.
  • the compression efficiency of the compressor is reduced, and a part of the intake air flows back along the inner surface of the intake hose which is connected to the compressor.
  • a blow-by gas is collected inside a cylinder block through the gap between a piston and a cylinder.
  • the blow-by gas is excessively collected inside the cylinder block, the engine may not operate normally, and thus, the blow-by gas collected inside the cylinder block is eliminated by being recirculated to the intake pipe.
  • a breather nipple is mounted between the compressor and the intake hose to receive the blow-by gas.
  • a fresh air nipple which supplies fresh air into the cylinder block is mounted to the intake hose to appropriately maintain the inner pressure of the cylinder block, and prevent the blow-by gas from being excessively concentrated.
  • the blow-by gas which is recirculated to the intake pipe through the breather nipple may reach the fresh air nipple by the flowing-back intake air. Since the fresh air nipple supplies fresh air into the cylinder block, the blow-by gas is moved back into the cylinder block.
  • blow-by gas intake air, exhaust air, mixed air, oil, and the like are present in the blow-by gas.
  • an air cleaner filter may be contaminated by the oil, thereby reducing the engine output.
  • the fresh air nipple may be clogged.
  • the fresh air nipple is clogged, it is not possible to prevent the adjustment of the inner pressure of the cylinder block, the excessive concentration of the blow-by gas, and the like.
  • the fresh air nipple may also be connected to a brake booster, and when the fresh air nipple is clogged by the oil contained in the blow-by gas, the brake may not be operated normally (e.g., may fail or malfunction).

  • the fresh air nipple may include a connection part disposed outside the intake hose, an extension part that extends from the connection part and is located inside the volume part, and a protrusion part that extends from the extension part into the intake hose.
  • the extension part may penetrate the center of the bottom part and the pocket part and the fresh air nipple may be integrated.
  • the total length of the extension part and the protrusion part may be greater than the depth of the pocket part, and may be less than the radius of the inner diameter of the intake hose.
  • a projection may be formed on the protrusion part.
  • the projection may be continuously formed on the outer circumferential surface of the protrusion part at a right angle with respect to the longitudinal center axis of the protrusion part.
  • Two or more projections may be formed to have spacing distances from the end portion of the protrusion part toward the inner sidewall surface of the intake hose.
  • the end portion of the intake hose may include a buffer part configured to absorb the vibration of the engine, and a perforated resonator may be mounted to the intake hose to approach the buffer part.
  • the perforated resonator may include a tubular body part fixed to the inner surface of the intake hose, and the body part may be formed with a plurality of apertures which penetrate the body part. The perforated resonator may be disposed closer to the air cleaner than the pocket part.

  • One side of the compressor of the turbo charger may be mounted with a breather nipple into which the blow-by gas flows and the recirculation nipple may be disposed between the breather nipple and the fresh air nipple.
  • the recirculation nipple may be mounted to the intake hose to protrude toward the inside of the intake hose.
  • the length of the recirculation nipple which protrudes from the inner sidewall surface of the intake hose may be about 5 mm to 10 mm.
  • the end portion of the fresh air nipple may be disposed closer to the center portion of the intake hose than the end portion of the recirculation nipple.
  • the recirculation nipple may be mounted to the intake hose and thus, the end portion of the recirculation nipple disposed inside the intake hose may be inclined closer to the compressor of the turbo charger than the coupled site between the intake hose and the recirculation nipple.

  • the pocket part may be formed on the inner sidewall surface of the intake hose, the oil contained in the blow-by gas may be collected in the pocket part even if a part of the blow-by gas flows back along the inner sidewall surface of the intake hose based on the running state, and thus, the oil contained in the blow-by gas may be prevented from flowing into the fresh air nipple.
  • the oil may be collected in the pocket part, or condensed in the protrusion which is formed on the surface of the fresh air nipple, thereby preventing the oil existing in the recirculated blow-by gas from flowing into the fresh air nipple. Since the perforated resonator is mounted to the intake hose, it may be possible to reduce the generation of noise caused by the intake air, and to prevent the oil from flowing into the air cleaner from the intake hose. In addition, contamination of the air cleaner by the oil may be prevented, and the fresh air supply to the brake booster may be prevented from being blocked.
